Linear PCM (LPCM) is an uncompressed audio format that is similar to CD audio, but with higher sampling frequencies and quantisations. LPCM offers up to 8 channels of 48kHz or 96kHz sampling frequency and 16, 20 or 24 bits per sample but not all at the same time. These values compare with 44.1kHz and 16 bits as used for CD audio. The maximum bit rate is 6.144 Mb/s, which is much higher than Dolby Digital or MPEG-2 coding. LPCM offers high quality (similar to DVD-Audio) but its high data rate leaves little bandwidth for video on a DVD video disc. Disctronics DVD-Video audio
